Title: An investigation into the presence of high levels of cadmium in sea-water samples from Mounts Bay, Cornwall
Author: R. Grantham
Document Type: Monograph
High cadmium concentrations were discovered in sea-water samples collected during an investigation into an algal bloom in Mounts Bay on the 5 and 7 August 1989. In response to this the Tidal Waters Unit of National Rivers Authority, South West Region, investigated the problem on 10 August 1989. Cadmium inputs via the freshwater, crude sewage and storm water overflows were assessed, and the cadmium content of the sediments, shellfish and seawater of the inner bay evaluated. All samples collected on 10 August, including sea-water samples, contained low levels of cadmium. No conclusive identification of the source of the cadmium originally found is possible, though it may be linked in some way to the algal bloom.
